Let me start by saying that I have more skill inside the case and training in take-appart than 99.99% of users due to AppleCare training. What I'm about to describe is a side effect of a side job I did for a friend with parts of unknown origin and I strongly discourage ANYONE from attempting this operation without training and an appropriately equipped lab. Last night I replaced the screen on a second generation (667Mhz without DVI) TiBook. This was a hellish experience that I will never voluntarilly repeat. After re-assembling the machine, zapping the PRAM and laying a curse on Jonothan Ives The machine rebooted and successfully cycled the screen..... sort of. It goes like this: Chime 2-3 seconds of odd, tiled patterning Jaguar Startup spinny, centered and normal Login screen, also centered and normal. (This is where it gets odd) Upon Login the screen "shifts" to the following: Screen image is compressed into 3/4 it's usual area, pinned at the upper left. Top Inch of image is echoed at bottom inch of screen with a two-pixel width gap between bottom of active screen area (Dock emergent edge) and the echo below it. Right edge of active screen area is roughly 1" from edge of LCD panel, last half-inch of visible desktop at right is "stretched", as if the whole 1/2" strip was getting the data for only three to five pixel columns. This is maddening. I've seen similar issues on other LCD's and I can't remember for the life of me what the solution was !! There are, of course, no monitor calibration tools in either the system, the AppleCare CD kit or the Open Firmware CDs ( Other than colour ) Ideas?
